IMPROVEMENT IN WAGON-BRAKE.

Specification forming part of Letters Patent No. 62,796, dated March 12,1867; antedated March 1, 1867.

To all whom it may concern:

Be it known that I, JAMEs F. Woon, 2d, of

Oohocton, in the coimty of Steuben, in the State of New York, haveinvented certain new and useful Improvements in Self-Acting Wagon-Brakesand the following is a full and exact description of the same, referencebeing I hadto the accompanying drawings, making a part of thisspecification, in which- Figure 1 represents a plan or top view of therunning-gear of a wagon. Fig. 2 shows a broken-01f section of theportion with the brake mechanism. Fig. 3 shows the edge. and top viewsof the adjustable angle-lever. Fig. 4 shows the metal link or slidethrough which the king-bolt passes to operate the brake.

Fig. 5- is a side view of the running-gear of the wagon with brakeattached. I

The object of my invention is an improvement on the one for which.Letters Patent were granted to me on the 10th day of May, 1864.

My invention or improvement consists in making the right-angle arm leverin two pieces,

so-that the cam is adjustable and can be va-' ried in length to suit thewear on the brakeblocks, the cam having its bearing on an in-.

clined plate, so as to operate surely and with ease; also, in having ametallic-plate slide, through which the king-bolt passes to form theconnection between the brake mechanism and the wagon tongue or pole.

To enable others skilled in the'artto make and use my invention, I willproceed to describe it more fully, referring to the drawings, and to theletters marked thereon.

The running-gear of the wagon being the same, or nearly so, asv thatshown and represented in my patent of May 10, 1864, it is not deemednecessary to explain it further than to show the alterations inattaching the pole A,

which is made to slide in between two forks or braces, a a, which arefitted in between the hounds b b. The metal-plate slide B rests up onthe perch or reach 0, it having an opening of sufficient length to giveit the necessary play. on the king-bolt. To the plate Bis theconnecting-bar c to the arm d of the lever D,

on the top of whichI make a series of notches, e, for the purpose ofholding the cam-piece E, where it is placed on the lever D. The campieceE has notches or teeth on its under side to correspond with the notchesor teeth e on v the .top side of the lever D. There is also a slot inthe piece E for a bolt or set-screw, f, to hold the cam to the lever.()n the brake-bar F I secure a metal plate, h, which has a protuberancefor the cam E to hold against.

When the brake-blocks i i are made they are to be of such size'that thecam E. is at the plate h on the brake-lever, as and for the purposesherein described. 1

2. The sliding plate B, hasp 7c, in combination with the sliding pole A,fork braces a a, and the brake-blocks i i, substantially in the mannerherein described, for the purposes set forth.
